Abstract: In gas detectors, such as may be used in computerized tomographic (CT) apparatus, it is necessary to provide electrical connections into the pressure vessel. Conventionally, these are by ceramic lead-throughs or similar. As gas detectors require an increasing number of individual detector elements, and therefore internal electrodes, the number of connections required increases and they are more closely spaced. This large number of connections can affect the integrity of the pressure vessel. This invention places a circuit board as a gasket between two parts of the pressure vessel, such as between a chamber and lid, so that conducting tracks on or in the circuit board provide the required connections. The invention is suitable for lead through for pressure vessels other than gas detectors of radiation.
Abstract translation: 在诸如可用在计算机断层摄影（CT）装置中的气体检测器中，有必要向压力容器提供电连接。 通常，这些是通过陶瓷引线或类似的。 由于气体检测器需要越来越多的单独的检测器元件，因此需要内部电极，所需的连接数量增加并且它们更紧密地间隔开。 这种大量连接可能会影响压力容器的完整性。 本发明将电路板作为压力容器的两个部分之间的垫圈放置，例如在室和盖之间，使得电路板上或其中的导电轨道提供所需的连接。 本发明适用于除辐射气体检测器之外的压力容器的引出。

Abstract: A hand and shoe radiation monitor is provided which includes a probe support body defining a plurality of cells, within each cell there being an ionization probe. The support body provides structural strength for protecting the ionization probes from force applied to the support body during a radiation monitoring event. There is also provided a fast response time amplifier circuit for the output from the ionization probes.

Abstract: A high speed tomographic x-ray imaging system comprises an array of x-ray sources disposed opposite a closely spaced array of x-ray detectors. Small groups of sources in the array are simultaneously pulsed to provide x-ray transmission data along a number of ray paths through a body undergoing examination. X-ray energy from each source in the array is collimated to illuminate only a small sector of the detector array. High speed, unambiguous x-ray transmission information, is thereby produced.

Abstract: In a device comprising one or a number of X-ray beams of suitable shape and at least one cell for detecting X-rays which have passed through the organ to be analyzed, the detection cells are ionization chambers comprising two parallel electrodes separated by a radiation-detecting medium for converting the X-rays to electron-ion pairs. The electrodes are connected to two terminals of a voltage source and the detection cells are associated with means for measuring the charge collected during a predetermined period of time under the influence of the X-rays.

Abstract: A miniature ionization chamber having a gas-filled housing which accommodates a guard electrode made in the form of a hollow perforated cylinder. The cylinder is electrically associated with the intermediate coaxial conductor of a triaxial cable used as the lead-in of the ionization chamber. The gas-filled housing of the ionization chamber also accommodates a collecting electrode shaped as a rod electrically connected to the center conductor of the cable and to tubular members. The rod is disposed internally of the guard electrode and is electrically connected, by means of jumpers passing through the holes in the guard electrode, to the tubular members. The tubular members embrace the guard electrode and are spaced a certain distance apart along its entire length. Arranged intermediate of these tubular members are spacers secured to the guard electrode and fixing the collecting electrode throughout its length with respect to the housing of the ionization chamber.
